“…The green emission peak at 520 nm is well matched with the energy value calculated by Lin [38], which is due to the energy difference between the bottoms of the conduction band to the zinc antisite level [38]. Most of the previous researchers attributed the green emission peak mainly to oxygen vacancy and zinc interstitial [13,37]. In the present work, we have also confirmed oxygen vacancy and zinc interstitial from E 1 (LO) mode in micro Raman spectra.…”

“…Its properties are highly depending on crystallinity, crystallographic orientation, crystalline size and morphology [9,10]. ZnO thin films are prepared by different coating techniques of physical and chemical routes [11][12][13][14][15][16]. Among all the techniques, the sol-gel spin coating process is a one of the simplest method to prepare thin film with different nanostructures with much ease.…”

Zinc oxide (ZnO) thin films were deposited by spin coating technique onto glass and fluorine doped tin oxide (FTO) conductive substrates. The effect of the Pedalium Murex (P. Murex) leaf extract on their structural, morphological, lattice dynamic and optical properties was investigated. X-ray diffraction studies revealed that the prepared thin films were polycrystalline. The crystalline size, lattice parameter, position parameters, bond length and texture coefficient were estimated from XRD studies. Morphological variations (cordillera, backbone and tree like structure) were observed for films coated with different quantity of extract. Lattice dynamics and defect studies were investigated using micro Raman spectroscopy, which revealed the presence of oxygen vacancies and zinc interstitial in backbone like structure. The excitation and emission spectra revealed that the optical quality of the ZnO thin films depends on defect concentration and excitation energy. Variations in intensity were observed for violet to green emission with deceasing excitation energy. The transmittance spectra of the prepared thin films were recorded using UV-visible spectroscopy. The film prepared with 0.01 ml extract exhibited low transmittance and band gap compared to other films. J-V curves were recorded for film deposited with 0.01 ml extract using polymer and liquid electrolyte as an electrolyte. The effect of the internal resistance was studied for the film deposited with 0.01 ml extract. The open circuit voltage (V oc ), short circuit current density (I sc ) and efficiency (g) of the constructed DSSC were determined.

“…A variety of techniques, such as chemical vapor deposition [12], atomic layer deposition [13], magnetron sputtering [14], pulsed laser deposition [6] and sol-gel [15] have been applied for the deposition of high quality ZnO films on glass substrate. In addition to the film quality, the preparation of large-area coatings with a cost effective technique is also an upfront challenge in glazing industry [7].…”

Ag nanoparticles (NPs) and/or graphene were incorporated into a zinc oxide (ZnO) photosensitive precursor solution. Then, directpatternable ZnO nanocomposite thin films were fabricated via photochemical metal-organic deposition. The transmittance and crystallinity of ZnO films were not almost changed but the resistivity of ZnO thin films was decreased by after incorporation of Ag NPs and/or graphene. Especially a double incorporation (Ag NPs and graphene) led to a greater decrease in the resistivity of the films more than the single incorporation (Ag NPs or graphene). This difference in resistivities was due to the combined enhancement of both the carrier concentration and mobility. The improvements in the electron concentration and mobility of ZnO composite films were largely dependent upon the introduction of Ag NPs and graphene, respectively. ZnO composite films could be direct-patterned without a photoresist and/or dry etching. Therefore, our results show that the cost of fabrication can be reduced by using a direct micro-patterning system and that the electrical properties of ZnO thin films can be improved by the incorporation of Ag NPs and graphene, while maintaining the structural and optical properties of the films.
